Thoughts (and occasionally fuming) about the state of science, fiction, and science fiction.

Science (and "science") news

"On 20 December 2013, The United Nations (UN) General Assembly 68th Session proclaimed 2015 as the International Year of Light and Light-based Technologies (IYL 2015)." (That's from the IYL home page.)

What could be more appropriate than a moment of respectful reflection (no pun intended) on the recent passing of a major pioneer of light technology? See "Charles Townes, who helped invent now-ubiquitous laser, dies." Lasers are essential -- to name only a handful of their applications -- to precision scalpels, retail scanners, DVD drives, telecommunications, and (now in field test aboard the USS Ponce) directed-energy weapons. That's quite the legacy.

Less commented upon, but also recent and noteworthy, "Illinois LED pioneers receive Draper Prize." That's Illinois, as in the university of: my alma mater. The Draper Prize (if less publicized than the Nobel Prize, one of which Townes won) is a Big Deal: the annual award of the National Academy of Engineering. Many a laser is, of course, an LED laser.

The Draper announcement speaks to me because -- decades ago, back at the U of Illinois -- I took a class on semiconductor physics from Prof. Nick Holonyak, the senior member among the aforementioned pioneers. Holonyak was a terrific teacher and, it was clear to me even then, a researcher doing groundbreaking work. He's now widely recognized for developing the first practical light-emitting diode. I am delighted on his behalf.

I've posted here often about computer (in)security, system vulnerabilities, hacking exploits, and privacy breaches. Most often such posts deal with all too common weaknesses of software design and implementation -- but hack attacks can also hide in hardware.

A state-of-the-art integrated circuit (such as the microprocessor or system-on-a-chip at the heart of your PC, tablet, or phone) can hold a billion or more transistors, and that complexity will only increase in future chip generations. How does one defend against malicious circuits hidden in such a sea of circuitry? You and I can't. The typical product manufacturer can't. The DOD wonders whether the manufacturers of their weapons, comm networks, and warning systems can. Hence it's encouraging to read "Stopping Hardware Trojans in Their Tracks: A few adjustments could protect chips against malicious circuitry."

Not that threats to our privacy and security are limited to hacking .... The drone your neighbor or his kid received for Christmas can be as intrusive as -- while much less technically demanding than -- a computer hack. Having said that, be of good cheer, because there may be a drone defense: "Rapere: An Intercept Drone to Seek and Destroy Other Drones." Seriously.

An opinion/prediction: augmented reality in glasses and contact lenses will catch on within a few years, for specialized purposes like hands-free access to reference materials. Example: a surgeon, mid surgery, superimposing an MRI image over the patient open in front of her. Example: a mechanic, up to his elbows inside a jet engine, doing a hands-free look-up of the next step in a maintenance procedure. For consumer use, IMO, AR specs will remain for awhile mere high-tech toys; we'll first see them break out as a consumer product in gaming.

Featured Post: A Milestone

On October 16, 2007, Fleet of Worlds was first published. That is: ten years ago to the day. Larry and Ed at 2015 Nebula weekend This...

Energized (Newly reissued!)

"A taut near-future thriller about an energy-starved Earth held hostage by a power-mad international cartel … Lerner’s vision of the future is both topical and possible in this crisp, fast-paced hard SF adventure.” —Publishers Weekly

Dark Secret (my latest)

"I heartily recommend Ed Lerner's Dark Secret" — Tangent Online

InterstellarNet: Enigma (I-Net #3)

"One of the most rewarding SF reading experiences anyone could ask for, on both an intellectual and emotional level." — Tangent Online

InterstellarNet: Origins (I-Net #1)

"One of the most original, believable, thoroughly thought-out, and utterly fascinating visions ever of what interstellar contact might really be like."— Stanley Schmidt, editor of Analog

A Time Foreclosed

"A nice little foray into the paradoxes of time travel" — SFRevu

Fate of Worlds (FOW #5)

“Brings to a stunning close a multivolume saga that has captured the imaginations of a multitude of readers … a story that will attract attention from series fans as well as readers of hard sf.” — Library Journal

Juggler of Worlds (FoW #2)

“A snazzy thriller/mystery that keeps us (and our hero) guessing until the very end ... Wide screen galactic scope, nifty super-science, crafty aliens, corporate corruption and cover ups, and a multi-leveled spy vs. spy vs. spy mystery with little being as it first appears make Juggler of Worlds a first class exemplar of pure SF entertainment.” —SFsite

Fleet of Worlds (FoW #1)

" ... Needs recommending within the science fiction community about as much as a new Harry Potter novel does – well, anywhere." —Locus

ARMAGEDDON / PARADISE -- two books in one

"A romp through time and history ... an intriguing selection." — Bookloons

Small Miracles

"Suspense and action enough to fuel any thriller, and even to drive it to the big screen." —SFrevu

Fools' Experiments

“When the artificial intelligences ... go maverick, they turn out to be the true weapons of mass destruction. A fast, fun read.” — Sci Fi Weekly

About Me

I'm a physicist and computer scientist (and an MBA, of less relevance to most of these posts). After thirty years in industry, as everything from individual technical contributor to senior vice president, I now write full-time. Mostly I write science fiction and techno-thrillers, now and again throwing in a straight science or technology article.
